Climate Change Makes Iberian Wildfires 40x More Likely, Study Finds

Extreme Weather and Wildfire Risk

• 🌡️ Hot, dry, and windy weather conditions that fueled Spain's worst wildfires in decades are now 40 times more likely to recur due to human-caused climate change.
• 🌍 Analysis from World Weather Attribution indicates that extreme conditions driving recent fires in the Iberian Peninsula (Spain and Portugal) are likely to recur every 15 years in today's climate.
• 📈 This is a significant increase from pre-industrial levels, where such events would have occurred only every 500 years with a 1.3° C lower global temperature.

Wildfire Intensity and Impact

• 📊 A daily severity rating metric, considering temperature, humidity, wind speed, and rain, is used to estimate wildfire potential and difficulty of extinguishment.
• 🔥 This summer, forest fires ravaged over 2.4 million acres in the EU, with Spain and Portugal accounting for approximately two-thirds of the total.
• ⚠️ The fires resulted in at least eight deaths, forced thousands to evacuate, and disrupted transportation networks.

Heat Waves and Climate Change

• ☀️ The wildfires coincided with a 16-day heat wave, the most intense on record.
• ⏳ Studies suggest that heat waves of similar intensity are now expected to occur every 13 years, compared to every 2,500 years in a world unaffected by man-made climate change.
